DYElNG-VAT..

SPECIFICATION forming part of Letters Patent N0.401,02'7, dated April 9,1889.

Application filed May 25, 1888. Serial No. 275,102. (No model.)

T @ZZ whom it may concern.-

Be it known that I, J AMES W. GREAvEs, of Providence, in the county ofProvidenceand State of Rhode Island, have invented a new and ImprovedDyeing-Vat, of which the following is a full, clear, and exactdescription.

My invention relates to an app'aratus for dyeing wool, yarn, andslnbbing, or other brous material, and t-he principal object is Io toavoid poling, as is now generally the practice; and to this end myinvention consists of a permanent or stationary vat combined with aperforated basket and a pressure-pipe eX- tending from the bottom to thetop of the basket, and through which the dyeing-liquid is forced by apressure of steam or by pumppressure. I

The invention also consists of the construction, arrangement, andcombination of parts,

zo all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

z 5 Figure l is a central sectional elevation of the complete apparatus,and Fig. 2 is a plan view of the vat with the basket removed.

A represents the permanent or stationary vat, preferably circular inform, and in the 3o center of which is mounted the vertical pipe B, towhich the openings a a lead.

C represents a steam or pressure pipe entering the vat A, and extendingalong the bottom thereof and entering the lower part of the verticalpipe B.

Opposite to the pipe C, or at some convenient part of the vat A, isjournaled the short shaft D, on the outer end of which is a pulley forrevolving the same, and on the inner end a pinion, D', with which meshesthe circular rack D2 at the bottom of the basket E, so that when thesaid shaft D is revolved the said basket E will be slowly revolved inthe vat, as will be understood from Fig. l.

The basket E is perforated at the bottom and sides, and is of lessdiameter than the vat A, so that a free circulation is permitted to allparts of the basket, and in the center of the basket is mounted thehollow sleeve E',

5o which surrounds the tube B, as shown in Fig. l.

The pipe B projects above the sleeve E", and on its upper end is placedthe perforated cover or spreader F, that covers the entire basket, andin the top of the pipe B is placed the short tube G, provided with thespreader Il, against which thc stream or jet of liquid forced up thepipe B strikes, and is deflected in all directions over'the perforatedcover F, so that a perfectly even distribution of the liquid to thebasket E and its contents is ef- 6o fected. l

J J are anti-friction rollers placed in the bottom of the vat A tosupport the basket E and cause it to turn easily.

In operation the yarn, wool, slubbing, or other material to be dyed isplaced in the basket E and the dyeing-liquid is supplied in suitablequantity. By means of a jet of steam entering pipe C the liquid isforced from the bottom of the vat through the pipe B and 7o thrown in acontinual spray on the top of the basket, which latter is at the sametime caused to'revolve. In this manner the coloring-liquid graduallysaturates the material and sinks to the bottom of the vat through thewool, dac., and is again carried up the center pipe. The operation iscontinued for a length of time sufficient to complete the dyeingprocess, thus leaving the material very evenly colored and in a stateundisturbed by poling, .850., as in 8o the common process.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The vat A, central pipe, B, held in the vat, 8 5 and the perforatedbasket E, placed upon the said pipe Band of less depth than the lengthof the pipe, in combination with the steampressure pipe C, entering thevat, and the pipe B, substantially as described. 9o

2. The vat A and perforated revolving` basket E, placed therein, incombination with a steam-pressure pipe, C, and vertical pipe B,perforated spreader F, placed over the basket, and the spreader H, heldabove the top of the pipe B, substantially as described.
